Understanding the Linux Kernel
This new edition covers Version 2.6 of the Linux kernel, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. Understanding the Linux Kernel provides a guided tour of the code that forms the core of all Linux operating systems. Beyond the functioning of the code, the book explains the theoretical underpinnings for why Linux, and many other operating systems, do things the way they do.
